This part of EN15437 defines the minimum characteristics for the interface between a trackside Hot Axlebox Detector (HABD) and Rolling Stock (RST) that comply with the European Directives for Interoperability to ensure that the minimum functional requirement of the interface is achieved. The minimum requirements of the interface apply to: a) Rolling stock conforming to standard European railway gauge, that is 1435mm; b) Rolling stock axles fitted with outboard bearings; NOTE The design of rolling stock axles fitted with inboard bearings should respect the requirements set out in Note 2 of 5.2. c) Rolling stock with a maximum operational speed of up to and including 250 km/h; NOTE 1 That is conventional rail and class 2 high speed rail rolling stock as defined in the rolling stock TSIs. NOTE 2 Interoperable rolling stock designed for speeds above 250km/h (class 1 high speed rolling stock) are mandated to have on-board equipment for axlebox condition monitoring. The requirements for on-board equipment are described in part 2 of this standard which is currently under development. NOTE 3 Interoperable rolling stock designed for speeds above 250km/h (class 1 high speed rolling stock) are outside the scope of this Part of the standard. However, if class 1 high speed trains are required to be monitored by HABDs their target area should comply with the requirements specified in this standard, except where stated otherwise. d) Trackside HABDs that are required to monitor conventional rail and class 2 high speed rail rolling stock. The rolling stock requirements of the interface are described in Clause 5 and for the HABD requirements of the interface are described in Clause 6.

This European Standard defines the minimum performance requirements of on-board monitoring systems for axlebox condition monitoring by means of temperature measurements.
This European Standard refers to temperature monitoring of the axlebox. However, the design may be such that the rolling bearing itself is monitored directly.
The requirements of this European Standard are intended to apply equally to basic monitoring systems for monitoring the axlebox temperature through to more technically complex systems that may employ a combination of mechatronics.
To ensure the compatibility of monitoring systems and the effective monitoring functions, this European Standard defines the requirements in the following areas:
- equipment and characteristics;
- monitoring performance;
- operation & Interface.
This part of EN 15437 does not include:
- systems that do not give an indication to the driver;
- how an on-board monitoring system is structured and how it measures the temperature and identifies axlebox position. This is considered part of equipment design and not part of the functional requirements set out in this standard;
- operational requirements for acting on the information reported by the on-board monitoring system;
- operational requirements for conflict of information between trackside monitoring systems and on-board monitoring systems;
- maintenance requirements for on-board temperature monitoring system.

This part of ISO 10218 specifies requirements and guidelines for the inherently safe design, protective measures and information for use of robots for an industrial environment. It describes basic hazards associated with robots and provides requirements to eliminate, or adequately reduce, the risks associated with these hazards.
This part of ISO 10218 does not address the robot as a complete machine. Noise emission is generally not considered a significant hazard of the robot alone, and consequently noise is excluded from the scope of this part of ISO 10218.
This part of ISO 10218 does not apply to undersea, defence, law enforcement, military and space robots, medical and healthcare, prosthetics and other aids for the physically impaired, service or consumer products, tele operated manipulators, and micro robots (displacement less than 1 mm).
NOTE 1 Requirements for robot systems, integration, and applications are covered in ISO 10218-2.
NOTE 2 Additional hazards can be created by specific applications (e.g. welding, laser cutting, machining). These system-related hazards need to be considered during robot system design. See ISO 10218-2.
